EEE is when a proprietary addition is made that affects interop with other conformant implementations of an open standard. This privacy feature does not alter how Chrome, FF, or Safari will render HTML or run Javascript, so it is not EEE. There's nothing stopping Chrome from implementing a similar (or better) feature in order to maintain or grow its market share!

We're in funny territory that Microsoft is using a Google open source project in a consumer-positive way that also happens to hurt Google's primary business, but because the feature addition to Edge does not affect interop with other browsers, I don't see how this is EEE.
